People don’t stop being trans because you disagree with them politically. I despise Jenner and other high profile trans grifters but I’m not shitty enough to deny their identities.
Do better. As a user of both sites this shit is genuinely upsetting. Despite how you may feel about hexbear, how can you claim that they bait people into revealing their internalized transphobia and then turn around and make shitty claims like this? I don’t give a shit if you call me a tankie or red fash or whatever, but I’m trans whether you like me or not.
You’re right, denying the reality of who a person is is a shitty thing to do. I dislike Hexbear as an instance and as a collection of individuals, they’re often appallingly behaved and I want nothing to do with people who routinely deny or attempt to justify mass murders because its politically convenient. However, who they are is who they are and I see no reason to assume that if they say they’re trans, they’re not without some actual evidence.
